So here's what I spent a few hours on today. I'm going to upgrade the headlights and turn signal bulbs this weekend. Going with Philips X-treme Power headlights and Stealthbulbs turn signals (chrome coated so you don't see amber until it lights up.)

 

Those lights look good. Are those Harley lights?

Edit: Yeah, I can't read!

 

Yup that's what the HD stands for in the topic

 

Very nice looking truck !!
Is that bedliner on the front bumper ?

 

Thanks. Yes it's Line-x'd. I'm going to have em hit it with the Line-X Xtra when I do my bed so it won't fade.

 

i recently did the same mod. all you guys looking to do this beware: there are package deals on ebay for the headlights that come with the harness upgrade *** well to convert the headlight socket. and its the around the same price as the ones w/o. i didnt know that until after i bought mine. ford charges around $85 each. do the math....lol oh btw truck looks good riggz, nice job.

 

Yeah but the wires are small. I got the kit with the harnesses, but I'm going to make my own upgraded harness kit w/ 14-12ga wire. The wire size looks to be 18ga.

 

i want to do the same thing, just not sure how or where to look to for info... any leads?

 

riggz, looks great! Two questions for you: do you mean you got the kit from eBay or somewhere else? Did they take off the plastic skirting (or whatever it's called) on the front bumper when they Line-X'd it?

 

You can buy the metra pack sockets and pins for under $6 to do both sides with 16ga wire. I used 14ga, so it was very tight, but it did fit into the socket. Then I built relays into the harnesses, all for under $20. I put the part numbers in my write up if you want to build it from parts.

 

nice writeup, where's a good place to find the connectors? Any local type store, or only online?

also, this place sells them with all the bulbs and a conversion harness 02 03 04 FORD F250 F350 SUPERDUTY 2007 HEADLIGHTS SET :eBay Motors (item 120399093518 end time Apr-08-09 10:49:15 PDT)
I'm guessing that these draw more current than those harnesses should be able to carry, thus your reason for using relays?

 

I got them at mouser

15422250 x2 $1.75/ea $3.50
12191819 x6 $0.20/ea $1.20
15366060 x6 $0.09/ea $$0.54

Then add wire and relays if you want them. I think mouser has a minimum order, but you can also try digikey and there is another place that I can't remember the name of. I am not sure if dellcity wiring does delphi connectors, but that would be another one to check if you don't need anything else.

I use the relays to draw power directly from the battery and avoiding drawing all of my current from the battery though minimum size wire to the headlight switch, back finally to the headlight bulbs. The relays use a shorter run of heavier wire and should show less voltage variation and lower voltage drop per amp.

 

The light bulbs don't drawn any more current than normal. However if you shrink the wire size you get more heat and less voltage. Using relays prevents the voltage drop issue and upgrading the wire size prevents both voltage drop and heat issues.

 

Delphi says the 15422250 connector has been replaced by the 13511996. The old part is made out of Nylon and the new one is made from PBT. It's about .5g heavier but that's the only difference I see. I'm wondering which one is better? Both have the same temperature rating of -40*c - 125*c. I'm going to try the newer parts. They are about $0.15 more each.

 

For $0.30 more, you might as well do the upgraded version.
